Most of the people that stores their cryptocurrencies usually use their phones to access them. Like me every time, I always make use of my smartphone If  I want to send cryptocurrency and my cryptocurrency wallet is also on my smart phone, installed. Maybe for a case like this,  the best you can do is to just also have or create an access to your wallet on your computer that you don’t carry around, and if anything should happen that you lose your smartphone and someone is likely to gain access to your wallet, you can quickly use your computer to access that wallet and lock it or move your funds to a different address or wallet.
